Trakia was a star system, a binary star consisting of one type F white star and one type G yellow star, located in the space of the galaxy's Delta Quadrant. (ST reference: Star Charts)
- Although Trakia in Star Charts was apparently intended to be the source of Trakian ale from VOY episode: "Vis à Vis", that beverage actually originates somewhere in the Alpha or Beta Quadrants, as per TNG episode: "Lower Decks".
